Legal claims defining the scope of protection, as filed with the USPTO.
1. A circuit configuration for protecting a MOSFET against overvoltages, comprising: at least one Zener diode connected in a blocking direction between a drain terminal and a gate terminal of a MOSFET to be protected; and a series circuit connected between said at least one Zener diode and a gate terminal of the MOSFET to be protected; said series circuit including a load path of a further MOSFET and a further Zener diode connected in the blocking direction, said further MOSFET having a gate terminal and said further Zener diode having a cathode connected to the gate terminal of said further MOSFET.
2. The circuit configuration according to claim 1, including a current source keeping the gate terminal of said further MOSFET at a defined potential.
